15.2 Date and time-of-day
For logging data recordings a real-time clock with date and time-of-day is pro-
vided. This real-time clock is buffered by means of the device battery; in the
event of battery replacement date and time-of-day are lost. The first line con-
tains the time-of-day on the left and the date on the right; by selecting this func-
tion these can be programmed in the format indicated. (see 9.4, 9.5)

15.3 Once-only output / saving of all meas. channels
Once-only manual measuring channel scans for acquiring the current mea-
sured values from all active measuring channels can be initiated by pressing
<MANU>
.

Each time the key is pressed again the measured values will be processed in
the same way with the associated measuring time.
15.4 Cyclic output / saving of all measuring channels
For cyclic recording and output of measured values the cycle must be pro-
grammed accordingly. The measuring operation can be
started
by pressing
<START>
and stopped by pressing
<STOP>
. Whenever a measuring operation
is started the maximum and minimum values from all measuring channels are
deleted.
In the course of a measuring operation the external memory must not be un-
plugged; this would cause all temporarily buffered measured values to be lost.
So long as no measuring operation has been started the
Cycle timer
function
displays the cycle previously set. Having selected this function you can specify
the cycle directly. (see 9.4, 9.5)
As soon as an operation is started the timer can be seen counting down to the
next cycle.
